IMPROVEMENT IN SKATES.

Specification forming part of Letters Patent No. 39,0!3, dated June 23,1863.

To all whom it may concern:

Be it known that we, MARTIN HRIsnL and MARTIN NADIG, of Rochester, inthe county ot' vMonroe and State of New York, have invented a new anduseful Improvement in Skates; and we do heieby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the'accompanying drawings, making a part of thisspecication, in which- Figure l is a verticallongitudinal section of thefoot-piece B, showing the combination and relative arran gement oftheseveral parts. Fig. 2 is a bottom view of the posts p p and their cap C,also the head t ot' the screw S.

This improvement relates to frame-skates; and it consists in thecombination of the double posts, which are provided at the top with arigidlytixed broad circular cap that constitutes a substantial supportfor the foot piece to rest upon, with the heelspur screw, the head ofwhich is so fitted between the posts as to prevent it from turning whilethe clampingnut is being screwed on, or when the spur is being attachedto or detached from the heel ofthe boot, and without the necessityofmaking a square hole through the cap and a corresponding square shankto the screw, all together constituting a simple, cheap, and verysubstantial attachment for the foot-piece, and at the same timeproviding a removable heelspur in this class of skates.

'The posts p p and pp and their caps O may be made of malleable iron,and each pair of postsand their cap be cast together, and for cheapmalleable-iron skates they may be cast to the runner; butin making steelskates We cut the runners from bars of the size they are desired to be,then draw one end down somewhat, and give it the desired curvature overa former, making all the runners uniform. A number of run ners are thensecured in a planerbed and recesses planed in their upper face toreceive the dovetail-shaped feet ofthe posts p p and p p', as shown bythe dotted lines a in Fig. 1. The foot or lower end of the posts arethen fitted into these recesses, Where they are firmly secured bybrazing. The rear cap, C, is then drilled, to admit the screw S, and thefront one is drilled and tapped to receive the screw S', or, if desired,they may be thus prepared previous to being attached to the runner. Thescrew S may be applied the same as the' screw S, if desired, it beinginserted from below and a clamping nut used. The head h of the screw Sis flattened on two sides, as seen in Fig. 2, so as to titbetween theposts p p, to prevent it from turning while the clamping-nut a is beingscrewed on, and to prevent its turning in the skate While it is beingscrewed into or out of the heel of the boot. The front end of the runneris let into the toe of the foot-piece B, as seen atf, Fig. 1. Thefoot-piece may be recessed, as seen in Fig. 1, to receive the collars C,or it may be set upon them, if desired. serted through the loops b.

The broad circular collars or caps O, more clearly seen in Fig. 2,constitute a very substantial lateral brace or support for the footpieceB to rest upon, and, as practice proves, enti-rely and eifectuallyprevents the lat-ter from being split by side thrusts or strains againstthe runner D. These annoying accidents are of -very frequent occurrencein the use of many varieties of skates heretofore manufactured.

Another source ofgreat annoyance to skaters is the failure of theheel-spur, in which case, when it is made, as in other skates of thisclass, by cutting the thread upon the upper portion ot the post, thelatter being rigidly fixed to the runner, a new ruimer must be suppliedsimply to provide a new heel-spur, whereas in this skate, which affordsall the advantages of the solid post and of the rigidly-fixed broad capO, or support for the footpiece, a removable heelspur is provided, whichalso clamps the parts together, and which may easily be removed at anytime and a new one substituted without disa-rranging any of the otherparts.

We claim as our invention- The combination of the removable heel-'spurclamping-screw S with the collar C and the double posts p p, the formerbeing cast to the latter, and they being rigidly attached to the runnerbybrazing or other equivalent means, all in the manner and for thepurposes specitied.
